RELAY-PHASE1 Wave A2/B/C/D/E (12-agent workflow, all tsc-clean, 314/314 tests pass): - A2: control-plane server.ts entry + boot/redis.ts revocation-bus wiring + start script. - B1: relay-run shared-store EnforceDeps (relay-auth ports over the SAME Postgres+Redis as P3). - B2: registry-backed MtlsVerifier (verifyAgentCert, fail-closed, INV14). - B3: store-backed RouteResolver (subdomain->hostId). - B4: Redis relay:revocations subscriber -> tunnel teardown (INV12). - B5: main-phase1.ts production entry (public bind, real TLS, async-mTLS prefetch bridge) + staging /auth/mint. - B6 (PARTIAL): relay-web operator login + browser DPoP; proof offered via term.dpop.<b64u> subprotocol. - C: agent dist/cli.js build (esbuild) + runTunnel run-loop + CliDeps. - D1: same-origin static serve of relay-web/public from the browser WSS. - E: systemd units + gen-ca/gen-capability-key/issue-tls-cert scripts + deploy/RUNBOOK.md. Adversarial review: all hard invariants PASS. Follow-ups (B7): close DPoP-subprotocol read on browser-server (blocks browser connect); rate-limit /auth/mint (F1); wire activeSessionCount (F2); scrub error logs (F5). Excludes unrelated public/style.css (concurrent iOS job).

# RELAY-PHASE1 · E (TASK E) — Private ENROLLMENT CA for agent mTLS.
|
|
#
|
|
# STAGING TEMPLATE. This mints the PRIVATE trust chain the rendezvous-relay uses to (a) verify agent
|
|
# client certs (SPIFFE mTLS, INV14) and (b) present the relay's agent-facing SERVER cert on
|
|
# AGENT_BIND_PORT so the dialing agent can authenticate the relay.
|
|
#
|
|
# *** THIS IS NOT LET'S ENCRYPT. *** The browser-facing :443 cert is public-web PKI and is issued
|
|
# by deploy/scripts/issue-tls-cert.sh. This CA is a SEPARATE, private trust root that must NEVER be
|
|
# a public CA — mixing them would let any web-PKI leaf enroll as an agent.
|
|
#
|
|
# Hierarchy produced (Ed25519, to match the control-plane dev signer's algorithm):
|
|
# root (self-signed, offline anchor)
|
|
# └── intermediate (signs agent SPIFFE leaves at CP /enroll, AND the relay agent-server cert)
|
|
# ├── relay agent-server leaf (TLS serverAuth, CN/SAN = the agent-facing host)
|
|
# └── (agent leaves are issued at runtime by the control-plane, not here)
|
|
#
|
|
# Outputs (0600 keys, 0644 certs) under CA_DIR (default /etc/relay/ca):

# CA_DIR output dir (default /etc/relay/ca)
|
|
# AGENT_FACING_HOST REQUIRED — CN/SAN for the relay agent-server cert; the host the agent dials,
|
|
# e.g. "<sub>.<BASE_DOMAIN>" (must match RELAY_URL's host in the agent config).
|
|
# AGENT_FACING_IP OPTIONAL — extra IP SAN (e.g. 8.138.1.192) if the agent dials the raw IP.
|
|
# RELAY_TRUST_DOMAIN OPTIONAL — SPIFFE trust domain (recorded in a NOTE only; agent SPIFFE leaves
|

# are minted by the control-plane /enroll, not by this script).

NOTE (staging integration seam, owned by the A-wave CP boot/ca-wiring, NOT by this script):
|
|
The control-plane's dev in-process signer must sign agent leaves with intermediate.key.pem so the
|
|
leaves chain to this bundle. CA_INTERMEDIATE_KMS_KEY_REF=dev-local selects the dev signer; point it
|
|
at ${CA_DIR}/intermediate.key.pem. Phase 2 replaces this with a KMS/HSM ref (§3.1).
|
|
SPIFFE trust domain for agent leaves = ${RELAY_TRUST_DOMAIN:-<RELAY_TRUST_DOMAIN unset>}.
|
|
|
|
*** root.key.pem is the offline trust anchor — after first use, move it OFF this host. ***
